Forms effused, crust‑like basidiomes that spread across wood as thin, flexible, violet to lilac patches. Fresh fruitbodies are soft, moist, and pliant, often with a smooth to slightly wrinkled hymenial surface. Colour ranges from deep purple‑violet in young areas to pale lilac, grey‑violet, or brownish‑violet in older or drier patches. The margin is typically whitish, fibrillose, or faintly zonate, sometimes developing short, reflexed lobes that give a bracket‑like appearance. When dry, the crust becomes leathery, duller in colour, and may crack or separate slightly from the substrate. The subiculum is thin, whitish to pale lilac, tightly adherent to the wood.
